SPECIFICATION forming part of Letters Patent No. 508,876, dated November 14, 1893.

Application filed August 3, 1893. Serial No. 482,691. (No model.)

T at whom it may concern.-

' Be it known that I, THADDIEUS S. FIELD, a

' subject of the Queen of Great Britain, and a resident of Atlanta, in the county of Fulton marked thereon, which form a part of this specification.

This invention relates as above stated to vehicle axles having however particular reference to that part of the axle intimately connected with the wheel, the invention consisting of certain details of constructionhereinafter fully set up and shown in the accompanying drawings, in which- Figure l is a plan of one end, approximately one-half of a complete axle. Fig. 2 is a side elevation of the part shown in Fig. 1, further showing the construction thereof. Fig. 3 is a perspective view of the axle-spindle, and Fig. 4: is a cross-section of the device between the bearing boxes.

In the figures like reference marks are uniformly employed in designating correspond-' ing elements of construction in all the views.

A is the axle-tree which is composed of two fiat bars of steel having considerable strength and resilience disposed edgewise vertically and parallel to each other. Between these spring-bars a are clamped bearing boxes b, two of same being near each end, one of each pair being at the extreme end and the others being a short distance therefrom toward the middle of the axle-tree. Running in. these bearing boxes b is a spindle B which is round bearing-box whereby the axle may be kept lubricated. By reason of the bars a being of resilient material this axle will spring laterally which allows the wheel to more easily surmount an obstacle, causes the jar incident to the first contact with an obstacle to be less,

and allows, especially, the wheel to mount a street railway rail and passover same without straining the wheel, this latter obviating a prolific source of accidents.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A spindle secured in blocks, said blocks being clamped between the extremities of two flat bars, and said bars so constructed and arranged as to have lateral resilience for the purpose specified. I

' 2'. The combination of two bars of resilient material disposed a short distance apart parallel longitudinally and placed on edge, bearing boxes clamped between each end of. said- THADDIEUS S. FIELD.
